which is better: Hed 3 or Zipp 404?
I have owned both. The Zipps are much lighter. Both are aero, since I race mostly long courses I am currently riding Zipps and love them (I have a set of 606s tubular).
Both good wheels …so I don’t think one is better than the other …just different characteristics.
I have 404’s that are great and I highly recommend.
